Abstract: MAGNETIC RECORD MEMBER FOR USE WITH ROTATING     HEAD MAGNETIC RECORDING APPARATUS                    Abstract An elongated magnetic tape has a pair of longitudinally extending servo track areas, one of which is closer to the longitudinal center of the tape than the other.  The lateral space intermediate the servo areas receives data signals, while the space between said one servo area and one edge contains identification and address signals.  The tape is par-ticularly adapted for use with rotating head recorders having two gaps on the rotor, with an intergap distance slightly greater than the lateral extent of the servo areas.  A recording or write gap precedes an immediately trailing reading or recovery gap.  When the rotor gaps pass the one edge in the one servo area, the write gap senses the servo track; while the read gap senses the identification signals.  The arrangement is such that prior to the time the write gap reaches the data recording area, the read gap has sensed the identifi-cation signals.  In a similar manner, when the gaps are leaving the data signal area, the write gap is sensing the other servo area; while the read gap is still sensing data.  The longitudinal extent of the servo areas indicates, respectively, beginning of tape (BOT) and end of tape (EOT).  A leader portion includes a magnetic coating for facilitating calibrating magne-tic recording apparatus to each particular article.

Abstract: ABSTRACT  OF  THE  DISCLOSURE      A process for the manufacture of ferric sulphate solution wherein ferric oxide is reacted with a molar excess of sulphuric acid at a temperature of 105°C. to 139°C. to form a hot slurry of sulphuric acid, unreacted ferric oxide, solid ferric sulphate and ferric sulphate solution.  The hot slurry is then diluted with water sufficient to dissolve all the solid ferric sulphate, the diluted slurry being maintained at a temperature of 20°C. to 60°C.  The unreacted ferric oxide is then separated to provide a product solution of ferric sulphate in aqueous sulphuric acid.  Unreacted ferric oxide is recycled for reaction with additional sulphuric acid.  The process provides ferric sulphate solutions suitable for waste water treatment and can employ ferric oxide available as a by-product of the metal industry.

Abstract: ABSTRACT OF THE DISCLOSURE      A system for imparting vibratory energy to solid particulate matter includes a resiliently mounted vibrator body, and a pair of counterweights on opposite ends of a rotating vertical shaft engaged with the vibrator body but adapted to rotate with the counterweights independently of the vibrator body.  A drive motor engaged with the vertical shaft rotates the shaft about its axis to rotate the counter-weights and thereby impart a relatively large amplitude vibratory motion to the vibrator body.  A closed conduit carried on the vibrator body contains solid particulate matter which travels in a fluidized condition along a linear path through the conduit in response to vibration of the vibrator body.  In one form of the invention, the vibrator body comprises a reaction chamber for receiving a gas flow and contacting it with an appropriate solid particulate catalyst contained in the reaction chamber and adapted to promote desired reactions between chemical components of the gas phase.  The vibrational energy imparted to the reaction chamber causes catalyst particles to flow in a continuous fluidized circulating path from the reaction chamber through a suitable catalytic regeneration chamber and back to the reaction chamber. Preferably, the drive motor is coupled with the rotating shaft of the vibrator body through a vertically extending torsion shaft having suitable torsional strength for required torque transmission but with sufficient torsional and lateral flexibility to prevent substantial vibrational energy from being transmitted by the vibrator body to the drive motor and its bearings.

Abstract: ABSTRACT     A mechanism for adjusting the circumferential position of a printing cylinder includes first and second meshing helical gears.  The helical gears are supported coaxially of the printing cylinder.  A first one of the helical gears is fixed to the print-ing cylinder to rotate with the cylinder.  The other of the heli-cal gears is supported for movement axially relative to the first helical gear to effect a camming action therebetween which ro-tates the first helical gear and thus rotates the cylinder.          However, upon axial adjustment of the cylinder, both of the helical gears move simultaneously axially with the cylinder.

Abstract: VALVE FOR VENTING THE INTERIOR OF A ROTATABLE HOLLOW ELEMENT          Abstract of the Disclosure A valve for venting the interior of a rotatable hollow element which is at least partially filled with liquid comprises a valve member which is movable transversely with respect to the axis of rotation of the rotatable element into and out of engage-ment with a valve seat to open and close a valve passage in which the valve seat is formed.  A spring maintains the valve member in closed position when the rotatable element is at a stand-still.        The valve passage has one end opening within the hollow member offset from its rotatable axis and the other end opens to the exterior of the element.  The major portion of the mass of the valve member is also offset from the axis of rotation but in a direction opposite from the end of the valve opening.  The mass of the valve member is such that at a predetermined rotary speed centrifugal force acting against the valve member will overcome the spring force to move the valve member away from the valve seat and to open the valve passage.

Abstract: ABSTRACT:        In a delta-modulation encoding arrangement ha-ving step-size control drift voltages and miss-match-be-tween the charge and discharge pulses for the first in-tegrating network in the feedback circuit produce an additional DC voltage on this integrating network. This additional DC voltage is compensated by an additional feedback circuit comprising a second integrating network.      However, if the signal to be encoded rapidly decreases from a large to a small amplitude and when after this rapid decrease the information signal only has a small amplitude an additional distortion is introduced for these small signals. To obviate this a modulation arrangement is included in the extra feedback circuit, which modula-tion arrangement is controlled by a control signal which derives a control signal from the delta modulation out-put pulses. The energy contents of the delta modulation pulses which are applied through the modulation arrange-ment to the second integrating network is varied in such a way that this energy contents decreases when the step-size increases and vice versa.
